Abstract:

The resistances to the phenyl pyrazole (such as fipronil), neonicotinoid and insect growth regulator insecticides (buprofezin) in brown planthopper, Nilaparvata lugens (Stl) were monitored by ricestem dipping method during 2006 to 2008. Results showed that N. lugens sharply developed resistance to fipronil following its immigration route in 2008. The levels of resistance to Fipronil in 10 immigration populations from 6 provinces in the Yangtze River Delta areas and the backmigration populations in Shaoguan and Shenzhen of Guangdong were moderate (resistance ratio 15.0-fold to 32.5-fold) and high (66.9-fold to 73.7-fold), respectively, higher than those of all 6 field populations from 5 provinces in 2006(2.6-fold to 5.8-fold) and 11 populations from 9 provinces in 2007 (3.2-fold to 8.4-fold). The above results suggest that N. lugens would develop a higher level of resistance to fipronil in most ricegrowing areas in China during 2009 to 2010. All populations collected in 2006-2008 showed high or extremely high level of resistance to imidacloprid, of which the resistance levels of 13 populations from 8 provinces in 2008 were 210.1-fold to 381.7-fold, though the resistance level dropped slightly in the following 3 years comparing with the extremely high level in 2005 (277fold to 811fold). For other neonicotinoid insecticides such as hiamethoxam, nitenpyram and dinotefuran, the resistance ratios were in the range of 20fold to 158fold, 07fold to 48fold, and 06fold to 28fold, respectively. All the populations were susceptible or lowlevel resistant to buprofezin (30fold to 119fold). In recent years, widespread and intensive use of fipronil for controlling two classes of migratory rice pest insects (brown planthopper/whitebacked planthopper and rice leaf roller) might be a major reason for fipronil resistance outbreaking in N. lugens. Therefore, to prevent insecticide resistance in N. lugens from outbreaking again, insecticide resistance management strategy including alternating and rotating insecticides without crossresistance need to be established.

摘要: 于2006-2008年采用稻茎浸渍法监测了我国主要水稻种植区大田褐飞虱种群对苯基吡唑类杀虫剂(氟虫腈)、新烟碱类及昆虫生长调节剂类杀虫剂(噻嗪酮)的抗性动态变化。结果表明,2008年褐飞虱对氟虫腈的抗性水平随其迁飞途径而出现急剧上升态势,其中,从我国南方稻区迁入长江中下游流域等6省10地种群和回迁至广东韶山、深圳两种群对氟虫腈抗性分别上升至中等水平抗性(15.0~32.5倍)和高水平抗性(66.9~73.7倍),明显高于2006年5省6地(2.6~5.8倍)和2007年9省11地(3.2~8.4倍)大田褐飞虱种群的抗性水平。上述结果预示2009年、2010年两年在全国稻区可能暴发褐飞虱对氟虫腈更高水平的抗性。自从2005年10-11月褐飞虱对新烟碱类的吡虫啉产生极高水平抗性(277~811倍)以来,近3年来抗性虽有一定程度下降,但仍处于高水平-极高水平抗性阶段,其中,2008年我国8省13地褐飞虱种群的抗性仍高达210.1~381.7倍。褐飞虱对其他的新烟碱类药剂噻虫嗪、烯啶虫胺和呋虫胺的抗性水平分别为 2.0~15.8、0.7~4.8和0.6~2.8倍。褐飞虱对噻嗪酮为敏感到中等水平抗性(3.0~11.9倍)。近几年来大量、广泛使用氟虫腈防治褐飞虱和稻纵卷叶螟两类迁飞性害虫是褐飞虱对其暴发抗性的重要原因。因此,必须及时制定全国范围防治两类迁飞性害虫的交替轮换用药抗性治理对策方案,才能延缓褐飞虱抗性的再次暴发。
